Today I was having a PE lesson while I fell down and hurted my foot. I was in great pain at that moment, but I tried to act as if nothing happened until the class was over. Though I had difficulty walk back to my classroom, but I still didn’t tell anyone and even refused the offer of help from my classmates. As the result, the hurt on my foot became worse. Now I know I am wrong. We can tell others our need for help and accept their help. Someday we can help him in return. In this way, we can get along each other happily and peacefully.
